The Strata Merino Quarter Zip Thermal Top is constructed using Nuyarn® technology, a lightweight, incredibly comfortable, and durable blend of Merino wool and nylon. By removing the twist of the yarns and drafting the fibers over a nylon core, Nuyarn® has produced a fabric with higher stretch and recovery, better moisture management, greater warmth and increased durability than traditional Merinos. It culminates to an itch-free, moisture wicking, and naturally odor resistant material to take the edge off in cool conditions.

Best ever!

I bought the Merino combo of pants and sweater last year and wear them several times a week. Whether on the motorcycle or on the sofa - they keep you super warm, and the quality is really great. I especially like the hood. I think I'll get another set in a different color to have a bit of variety.

Alles bestens. Herzlicher Dank

Strata sweater

Love that it’s merino and the hood comes off. And the thumb holes!


I am so impressed with this base layer! They put a LOT of thought into the quality and construction of this top. YKK zipper and snaps, reinforced stitching, no tags and a perfect fit. I am 5’10 and weigh 165 lbs. and the small fits perfectly. I wear it as a base layer even when I'm not riding because it fits and feels so good. The hood is the ideal shape/size to wear under your helmet too.
Overall, it is worth every penny and I could not be happier!

Fantasy on and off the bike

I have two for myself and have given three as gifts! Great fabric weight and typical Mosko attention to detail. The removable hood fits cleaner and better than normal hoods and I can reasonably wear it under my helmet. Great item.

You must be a great guy to have as a friend, Bill! Thanks for choosing Mosko for yourself, and for your peeps!
